    Controlled, Repeatable Lubrication

    The Duo fluid controller delivers controlled, repeatable coil stock lubrication for narrow-width stamping applications. With Duo, you conserve lubricant by applying only what you need, directly to the stock, without overspray or excess fluid mess.

    Duo delivers stamping fluid to a Mini-Roller or Uni-Roller® S2 which then applies it neatly to one or both sides of the stock. The Duo controller is designed for painless integration: Simply attach the provided rotation sensor cable, fill the lubricant reservoir, and mount and plug-in the Duo controller to get started. Adjust the frequency and duration of lubricant dosing and let Duo provide worry-free, consistent lubrication while you focus on making parts.

    • Consistent lubrication protects dies & improves efficiency
    • Reduces stamping fluid consumption significantly
    • Neat lubricant application keeps press areas clean
    Combine Duo with either Uni-Roller® S2 or Mini-Roller applicators.

    The Internally-Fed Difference

    Unist’s unique internally-fed roller design wicks and transfers a controlled amount of lubricant to the stock. Only what is needed is used - saving fluid and preventing messy, wet press areas.

    Supplemental / In-Die Spray

    The Duo controller can also be used to control two Unist Airless Spray Nozzles for jobs where critical die components require additional lubrication.
